Lenovo has introduced its latest line in ThinkPad laptops, touting the new machines' affordability, eco-friendliness and "military grade durability".
On offer, the 14in L412 and 15in L512. Both series come in versions equipped with Intel Core i3 and Core i5 processors. Some models use the graphics cores integrated into the CPUs …

Dell's been doing that for years

Greenwash

"Some 30 per cent of the L412 is made from old bottles and so forth"

That'll be 30% by volume or weight I guess - whichever has been chosen to give the largest figure. Certainly not value or embodied energy. In fact it might take considerably more energy to make the recycled case than to use virgin materials.

And how much less power does it consume than a bog-standard laptop?

Don't be taken in. Anyone who buys one of these thinking they're saving the planet is seriously deluded.
